This example displays a centered greeting message using the D3.js library. The visualization is created by applying the `select` function from D3 to target the `#message` div element in the HTML document, then setting its text content. The code imports the `select` API from D3 and also imports a local ES6 module called `myMessage`, which exports the string 'Hello VizHub!'. The message is rendered with large, centered font styling defined in the accompanying CSS file, and the D3 library is loaded via a CDN link in the HTML structure.
